The answer is y=10+4x

Mr. West estimated a mass to be 265g, but upon carefully measuring it, found the actual mass to be 240g. What was the percent error?

Answers

Answer:

The answer is 10.42 %

Step-by-step explanation:

The percentage error of a certain measurement can be found by using the formula

[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]

From the question

actual mass = 240 g

error = 265 - 240 = 25

So we have

[tex]p(\%) = \frac{25}{240} \times 100 \\ = 10.41666666...[/tex]

We have the final answer as

10.42 %

Answer: y = 1/2 in decimal form = 0.500

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*y+3-(4*y+2)=0

olve  :    -2y+1 = 0  

Subtract  1  from both sides of the equation :  

                     -2y = -1

Multiply both sides of the equation by (-1) :  2y = 1

Divide both sides of the equation by 2:

                    y = 1/2 = 0.500

Jerome hiked three-fourths of a mile in two-thirds of an hour. What was his hiking speed in miles per hour?

Answers

3/4 / 2/3 is 9/8 which is 1 1/8. When you did ode fractions you use “KFC” Keep the first fraction the same you Flip the sign from divide to multiply and you change the last fraction by flipping the numerators and denominators around

The value of his hiking speed in miles per hour will be;

⇒ Speed = 9/16 miles per hour

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Jerome hiked 3/4 of a mile in 2/3 of an hour.

Now,

Since, Jerome hiked 3/4 of a mile in 2/3 of an hour.

Hence, We can formulate;

⇒ Speed = Distance / Time

⇒ Speed = 3/4 / 2/3

⇒ Speed = 3×3 / 4×4

⇒ Speed = 9/16 miles per hour

Thus, The value of his hiking speed in miles per hour will be;

⇒ Speed = 9/16 miles per hour

I
. During a volleyball training session, Idalie drank twice as much water as Adamaris, and Jonathan
Arank 100 mL more water than Idalie. Between them they drank 3 liters of water. How much water
did Adamaris drink?

Answers

Answer:

Step-by-step explanation:

Let's say I = amount of water Idalie drank,

A = amount of water Adamaris drank

J = amount of water Jonathan drank.

We are told Idalie drank twice as much water as Adamaris. You can write it as:

Idalie = 2 times Adamaris

I = 2A

Then we are told Jonathan drank 100ml more than Idalie. So

Jonathan = 100 + Idalie

J = 100 + I  (and we know I = 2A)

J = 100 + 2A

Between them they drank 3 liters (3L = 3000ml) of water.

Idalie + Adalie + Jonathan = 3000

I + A + J = 300

So since we know I = 2A and J = 100 + 2A, we can put it into the equation above:

2A + A + 100 + 2A = 3000

Gather the like terms and you get:

5A + 100 = 3000

Subtract 100 from both sides.

5A = 3000 - 100 = 2900

To find A, divide both sides by 5

A = 2900/5 = 580

This means Adamaris drank 580ml of water
